The flapper in my toilet tank falls back into its resting position
about halfway through the flush and prevents the tank from emptying
completely.

The flapper is attached to the overflow pipe by two flexible "legs",
it's made of rubber and its centre consists of a hollow cone of rigid
plastic with a hole in it.

Can anyone offer advice on how I can get the tank to empty completely?

Thanks in advance for your help.

Buy a new flapper. I believe that air is supposed to be trapped under
the flapper and keep it open until the water level in the tank drains.
If the flapper is closing too early it would seem this is not happening,
or you have the wrong flapper.
